Wooden article to be coated must be dry & free of dust & loose particles. Prepare smooth surface by sanding with emery paper # 180 followed by # 320 or # 400. Cracks if any should be filled & levelled.
Apply one or two coats of WOODPOL Interior PU clear sealer depending upon surface smoothness and allow it to dry for minimum of 8 hours. Sand with emery paper # 320 or # 400 between application of successive coat.
Select Finish coat available in Glossy & Matt. Apply one or two coats of WOODPOL Interior PU – clear and allow it to dry for minimum of 8 hours. Sand with emery paper # 320 or # 400 between application of successive coats. For better protection apply an additional coat.
» Stir the contents well before use since soft sedimentation may occur in matt and sealer finish on storage. Strain through musclin cloth in glass or plastic container. Mixing pot, stirrer & spray gun should be free of moisture since system is sensitive to moisture.
» Mix only required amount of Base & Hardner to be used. Do not transfer unused or Left-over material after used into original container as it cause the whole container to gelled up.
» Use within one week after opening Base & Hardner container.
» Since system have limited Pot-life (after mixing Base & Hardner) after which they should not be used.
» Recoating and Hard dry time may be more in case of high humid conditions and/or low ambient temperature.
» Coverage & dry time varies depend on film thickness, quantity of thinner used & nature of wood.
